Answer:

unfortunately no

Step-by-step explanation:

with ± (plus-minus) sign, you have to work out the two cases.Therefore there're two solutions for this question i.e

[tex]x = \dfrac{ \pm4i}{-2} \implies x _{1} = \dfrac{4i}{-2} \: \: \text{and} \: \: x _{2} = \dfrac{ - 4i}{-2}[/tex]

and this simplifies to [tex]x_1=-2i,x_2=2i[/tex]
